Abstract

Abstract

In order to further improve the grade of vanadium-titanium-iron concentrate and realize the policy of blast furnace concentrate, the process mineralogy of vanadium-titanium magnetite concentrate produced by a concentrator in Baima mining area of Panxi was studied. It is pointed out that the presence of guest minerals in titanomagnetite affects the theoretical grade of iron concentrate, which is the main reason why it is difficult to improve the grade of vanadium titanomagnetite concentrate. Through laboratory and industrial tests, it is proposed that the content of SiO₂, MgO and Al₂O₃ in iron concentrate can be effectively reduced by increasing the grinding fineness for deep separation, and the grade of iron concentrate can be further improved. The research results have been applied to a concentrator in Baima mining area and the grade of V-Ti-Fe concentrate has been increased from 55% to over 57%, thus effectively increasing the supply and maintenance capacity of high-grade V-Ti-Fe concentrate in smelting system, improving the economic benefit of the whole steel production line, which provides a technical route for improving the grade of vanadium-titanium magnetite concentrate in Panxi area.
